Add "Copy to Clipboard" to the "Copy login command" page

[chrgraefe]

On the "Copy login command" there are serveral token to authenticate against OpenShift.

Your API token is
sha256~123456789abcdefghijklmonABCDEFGHIJKLMNOPQRS

Log in with this token
oc login --token=sha256~123456789abcdefghijklmonABCDEFGHIJKLMNOPQRS --server=https://api.server.com

Use this token directly against the API
curl -H "Authorization: Bearer sha256~123456789abcdefghijklmonABCDEFGHIJKLMNOPQRS" "https://api.server.com/apis/user.openshift.io/v1/users/ ~"

Every single user has to click on that, select it and copy to clipboard. There should be a "Copy to Clipboard" button near every token to make it easier to do just that.
